Puppy

Puppies begin to learn to live with others. Behaviours learned in this phase will have a huge impact on a puppy’s life. This stage sees small and medium breed puppies approaching physical maturity, while large and giant breeds can take 18 months to 2 years to reach their adult size.

The key stages of puppy growth

Nutrition

This is a key stage in the physical and sexual development of puppies, so ensuring they are eating food designed to meet the needs of this specific developmental stage is vital. See our puppy nutrition guide for more information, or take a look at our puppy products.

Health

This is a good time to start to set activity and exercise schedules for your pet. Getting into good habits now will aid development and set your puppy up for a healthy future. Speak to your vet about a vaccination schedule and whether you should consider spaying or neutering your puppy.

Development

Much of a puppy's height and muscle growth happens between six to nine months, depending on the breed size. Milk teeth are replaced by adult teeth, and an adult coat replaces the puppy coat. Somewhere between six to 12 months your puppy will begin to lift his leg, or enter her first heat period.

Behaviour

This is the stage where structure, activity and boundary reaffirmation are vital. Puppies have a natural capacity for learning at this age, so it's important that lessons learned during this time need to be adhered to, and training and wider socialisation needs to be maintained. This will help your puppy develop into a confident, well-behaved adult dog.

Environment

Ensuring that your puppy has their own set places for eating and sleeping, as well as a range of toys to play with, will help with natural development and understanding of basic house rules. Exploring a range of outdoor environments and being exposed to new experiences will stimulate learning, breed self-confidence and generate a stronger bond between puppy and owner.

Large and giant breeds

The growth process for puppies differs depending on their breed size. Large breed dogs can take up to 18 months to reach full maturity, while giant breeds are not considered fully grown until 2 years old. Up to eight or nine months, large and giant puppies experience rapid skeletal growth, with the remaining months focussing on developing muscle until they reach their adult bodyweight (70 times their birthweight in large breeds and 100 times their birthweight in giant breeds).
